Various applications of electrical resistors

Heating of water lies in electrical resistors that, in different dimensions, ensure an adequate heat flow

The needs of the users have become enormous, so much so as to bring the companies develop entire departments of research and development to follow the logic of the market and satisfy their customers.
Even in the world of hydraulic fittings this trend has been felt, not only in the purely tertiary retail, but also in the primary and secondary where raw materials are processed to obtain usable components such as in boilers and kettles as electric resistors.
They are made of copper, a metal that has an essential feature for the purpose to which the electrical resistances are subjected. In fact, copper has an excellent resistance to corrosion, which makes it perfect for the intended purpose.
In fact, electric resistances must resist to corrosion in environments with particular conditions such as temperatures near or above 100 degrees and pressures superior to that of ambient. Copper creates a protective layer that protects an electrical resistor.
Besides, resistors operate at a voltage which is typically of 220 V single-phase and, in some cases, models can be used ranging from 110 up to 240 Volt. There are also available electrical resistors which require powers ranging from 1000 to 3000 watts, depending on necessary production requirements.
